TO ALL WHOM IT MAY CONCERN: Y

Be it known that I, ADRIAN RAIS, of Waterbury, in the county of New Haven, and State of Connecticut. have invented u. new and improved Rotary Dial-Plate Butt-HingeMachinc; and I do hereby declare that the following is n. full, clear, and eignet description thereof, which will enable those skilled in the art to make and use tlxe'same, reference being had to the accompanying drawings, forming part of' this specification, in which- Figure 1, sheet 1, represents a plan of my improved rotary dial-plate butt-hinge machine.

Figure 2, sheet 1, is a detached view of the rotary-dial-plate having the top plate removed.

Figure 8, sheet 2, is an inverted plan or bottom. view of my invention.

Figure 4, sheet 2, is a vertical section taken in the irregular line :c fr, fig.V 1.

This inventionrelates to improvements in machineryfor making butt-hinges; und consists in a mechanism so constructed 'that the-two right and left match-blanks, 'which form a butt or hinge, shall be conveyed from l feed-hoxes respectively, by automatic devices, to and upon the periphery of dial-plates or disks, which rotate and rstpresent the blanks to dies for bending the knuckles, afterwhich operation they are presented to the mills, and after ,they have been milled, nre carried opposite and introduced into a nailing device, where the match-blanks are united and fastened together by the nail or /rivet, and when thus finished are discharged from the machine. The whole operation is therefore automatic and continuous from beginning to end.

. In the construction of" my improved rotary butt-hinge machine, I have employed mechanical devices for accomplishing the several details of the operation in the manufacture of a hinge similar to those which have been described in previous applications made by me for Letters Patent; and the distinguishing and essential feature of this invention consists in employing circular dial-plates or rotary disks divided into equal segments, each of which carries a radio1 slide that receives the hinge-blanks from feed-boxes successively, and conveys the blanks in front of devices for bending the knuckles, milling them, `joining the rights and lofts, and nailing them, all of which operations are performed in regular order and simultaneously, as hereinafter more particularly described.

vthem by :ii-ins c e that are attached to slides E E connected with side levers G The machinery is supported on a suitable frame or bed, A, across one side of which' is 'placed a main driving-shaft, B, on which are duplicate camsl and cranks for actuating the scvcral'deviccs arranged in pairs for performing'thc several operations on the blanks. First in order ingthe arrangement of devices are the two vertical feed-boxes C C for holding the blanks, one on one sido of the frame for tho right-hand and the other on the opposite side for the left-hand blank. In front of thc feed-boxes C G arc placed the rotary diahplatcs or disks-D D, .which are actuated by spring-pawls a a pivoted upon slides E E that are connected by rods 6 with plate-crunks F I sct on opposite ends of the driving-shal`t B. 4The pawls a acutch in notches a (l.1 made in the periphery of the disks D D at cquidistnnt points between radial slides numbered 1, 2, 3, 4, 5, 6, 7, 8. When the cranks turn and draw the slides E E the pawls a e push the dislks D D one scgmcntor one radial slide ut a time, and the motion of' the disks is simultaneous. Spring-dogs a2 a are placed onl one side of the disks -D D, so that when the pawls a a have performed their work the dogs shall also catch in the notches al al and hold the `disks ixedly while the blanks are operated on by the bending-dies and mills, us hereinafter described. he springdogs a2 a2 are released fronrthe notches a' al by the slides E E on their return movement with the pawls a a, by striking against the ends of the dogs which are pivoted atthe opposite ends, and arc provided with springs to force the dogs into the notches ct a. The radial slides 1, 2, 3ctc., are fitted in recesses in the disks D D, and are held in them by a stationary top plate, D. The radial slides have pins c c which Iwork in slots in the disks. I The inner ends oi' the slides bear upon :i ring or coil-spring, d, in the middle of thc disks, which spring yields and allows the slides to be pushed back, but forces them outw distant from thecentre,

inward, .as shown in 2. The disks D D are so arranged that when they rotate, corresponding radial slides 1n the disks take their position opposite the fcetbbo'xes C C to receive the hinge-blanks, which are pushed upon G, which are actuated by side cams H H to move the slides El El in one direction, while they are moved by spiral springs in the other direction. After the radial slides have received the blanks from the feed-boxes the disks are moved by the paivls a a, as'bef'ore described, to convey the blanks in front of the dies ffl, which turn up their edges preliminarily to bending the knuckles, as shown in 6g. 5. The dies ff rise through the bed A and push the edges of the blanks up against adjustable dies ff secured 'in posts gg fixed in the bed. They are worked by levers Gl G4 placed under the bed and actuated by cams Hl Hl. The next movement oi the disks carries the blanks opposite the pushing-slides EZEZ, in the ends of which are set the dies for finishing the Aoperation of bending the knuckles,

as shown in fig. 4. This operation is effected by tho slides E2 E2 which are connected with 'cranks F F. The -slides E2 Ez mvo up and press against the ends of the radial slides, and push them in the disks far enough to permit the knuckles to be turned while the blanks are held rigidly'- by overhangblocks-gl y' fastened on the top plate D1 by set-screwls. The radial slides bear upon the coil-spring-d, which yields te the pressure and allows them tobe pushed back for this operation; and when thc pushing-slldcs E2 E2 nrc' withdrawn the spring d throws the radial slides forward again into'their original position. The rotationof the disks next conveys theblanks opposite the mills I I, into which the knuckles are pushed by sub-slides h h connected with levers (nl2 Gf2 that are actuated by the slides E2 E having connecting-rods g'l g2, The mills I I are operated as usual with independent pulleys c 7c. When the blanks have been milled they are next conveyed in front of the central nailing device J, where the rights an'd lofts are received on opposite sides by slidesh1 hl, which move out by means of levers G Gr"i placed under the bed A, and actuated by side cams Hz Hz. The blanks are pushed lfrom the radial slides ou to the slides -t t by arms e el attached to the slides E El, that are actuated as before described. The blanks are received from the feed-boxes C C on the radial slides at one side of the disks j:at the same time that they are delivered to the nailing device on thc opposite side. The slides t z, after receiving the blanks from the radial slides, carry them into the nailing device J, where the knuckles of the rights and lefts are joined to form a hinge and receive the nail or rivet which holdsv them together. The nails er rivets are held in a. feed-box, Cl, and when the blanks have been united a nail is pushed into the knuckles by a nail-red, m, connected with a slide, E", that' is actuated by the cam H3 in one direction, and is moved in the other direction, to withdraw the nail-rod m, by a spiral spring, d. Thus the rotary, disks DDsuccossively receive-the blanks from the feed-boxes C C and convey themen the radial slides to this devices forbending the knuckles, milling and nailing, all of which operationsproceed automatically and simultaneously.

Havingl described my invention, I claim as new, and desire/to secure by Letters Patent- The rotary carrying disks D D, with radial slides for receiving the right and left hinge-blanks from the feed-boxes C C and conveying them successivelyto the bending, milling, and nailing devices, constructed and operating substantially as herein shown and described.

2. The pawls a a connected with thel slides E E, 'in combination with thc rotary carryingr disks D D, all constructed, arranged,'and operating substantially as and, for the purpose herein described.

3'. The spring-dogs a: a, iu combination with the rotary carrying disks' l) D, al-lconstructed,arranged, yid operating substantially as and for the purpose herein-described.

1l. The slides El Erprovided with the arms e e, in combination with lthc rotary carrying disks D D, arranged and operating substantially as and for the purpose heroin described.

v5. T/he combination ofthe rotary carrying disks D D with the devices described for bending, milling, and nailingthe hinge-blanks, the said combination being organized and operating substantially asherein shown and described.
